LOUIS W. DE YOUNG, OF LEBEC, CALIFORNIA.

TROLLEY-WI-IEEL SUPPORT.

To all whom it may concern Be it known that I, LOUIS IV. DE YOUNG, acitizen of the United States, and a resident of Lebec, in the county ofKern, in the State of California, have invented certain new and usefulImprovements in Trolley- Wheel Supports, of which the following is aspecification.

My invention relates to supports for trolley wheels for electric railwaycars, and the objects of my invention are, first, to provide a trolleywheel support in which the wheel is pivotally mounted for lateralmovement on its support, whereby the same will readily follow thetrolley wire in traveling around curves and passing over switches,second, to provide such a support that the wheel will be normally inline for traveling along a straight wire, third, to provide such a support in which springs, which are liable to get out of order, areeliminated, and fourth, to provide such a support that is simple ofconstruction, durable and easily installed.

With these and other objects in view as will appear, my inventionconsists of certain novel features of construction, combination andarrangement of parts as will be hereinafter described in detail andparticularly set forth in the appended clain1s,reference being had tothe accompanying drawings and to the characters of reference thereon,which form a part of this specification, in which Figure 1 is a sideelevational view of my support with the wheel mounted thereon, showing aportion broken away and in section, F 1g. 2 is a front elevational viewof the harp of my support with the wheel mounted therein. Fig. 3 is aside elevational view of the harp without the wheel, shown in a slightlymodified form, and Fig. 4 is a perspective view in detail of the hearingupon which the harp rides.

Similar characters of reference refer to similar parts throughout theseveral views.

The shank piece 1, harp 2 and bearing 3 constitute the principal partsof my trolley wheel support. The shank piece 1 is provided with a socket1 adapted to fit tightly onto the upper end of the trolley pole, and itis provided with double lugs 1 and 1 and with a slot between the lugmembers so that it may be clamped onto the trolley pole. It is providedwith an upwardly extending guard portion 1 adapted to guard the wirefrom catching under the lower surface of Specification of LettersPatent.

the wheel in case the trolley wheel leaves the wire. This shank piece isalso provided with another socket l at an angle to the socket 1 Thissocket is adapted to normally hold the harp in a vertical position, andis provided in its lower end with a hole 1 In the bottom of this socketl is set the bearing piece 3, which is shaped as shown best 1n Fig. 4:with two oppositely disposed double beveled surfaces 3 and 3 and it isfastened therein by means of a screw 3. Mounted in this socket on thetop of this bearing piece 3 is the journal 2 Its bottom surface isadapted to fit the beveled upper surface of the piece 3 when in theposition as shown in Fig. 1; but in case the harp is turned, it willride upon the bevel surfaces. The trolley pole being provided with aspring at its base will cause an upward thrust of the support at alltimes, which will allow the trolley in case it leaves the wire to assumeits normal position as shown in Fig. 1. Upon the upper end of thejournal2 is the harp which is integral therewith. This harp is suitable for theordinary trolley wheel which is mounted therein in the usual manner. Onthe lower end of this journal 2 is provided a reduced eX- tended portion2 which extends downwardly through the bearing 3 and the hole I in thesocket 1 and in its lower end is provided a cotter pin 2 which isadapted to prevent the journal 2 from withdrawing from the socket incase the trolley leaves the wire, but it is placed a sufficient distancebelow the bottom of the socket to allow a free movement of the journal 2on the bearing 3.

In the modified construction, as shown in Fig. 3, there is added to thelower extended surface of the journal 2, a pin 4: extending through theextended portion 2 which provides a less bearing surface for the journalE2 upon the bearing 3.

Though I have shown and described a particular construction andarrangement of parts, I do not wish to be limited to this particularconstruction and arrangement, but desire to include in the purview of myinvention, the construction and arrangement substantially as set forthin the appended claims.

It is obvious that with this construction, there is provided a supportfor trolley wheels that is simple and economical of construct-ion; thatwill hold the trolley wheel normally in line with the trolley wire witha minimum of friction on the wire, and with only a slight pressure uponthe wheel in case of curves, and the like, which will cause the journal2 to ride upon the bearing 3 and allow the harp to turn, but after thecurve is passed and the line is straight the Wheel will immediatelyassume its normal posi-.

tion; that the parts may be easily removed in case of Wear, and thatthere are no springs or other parts liable to breakage.

Having thus described my invention, what I claim as new and desire tosecure by Let ters Patent is 1. A trolley wheel support comprising amain shank piece provided with a socket adapted to be fitted over and berigidly secured on the upward extending end of a trolley pole, providedwith an upwardly extending guard piece and also provided with a normallyvertical socket portion therein, a bearing with its upper surfacebeveled to provide two double angles on opposite sides thereof looselymounted in said latter mentioned socket, means for holding said bearingfrom turning therein and a trolley harp provided with a downwardlyextending journal portion adapted to fit into said socket and its lowersurface to conform to the upper angled surface of said bearing piece,provided with a reduced extended portion.

2. A trolley wheel support comprising a main shank piece provided with asocket adapted to fit over and be clamped on the upward extending end ofa trolley pole, provided with an upwardly extending guard piece, andalso provided with a normally vertical socket portion provided with ahole in the bottom thereof, a bearing with its upper surface beveled toprovide two double angles on opposite sides thereof loosely mounted insaid latter mentioned socket, means for holding said bearing fromturning therein, a trolley harp provided with a downwardly extendingjournal portion adapted to fit into said socket and its lower surface toconform to the upper angled surface of said bearing piece, provided Witha reduced extended portion extending downwardly through said bearingpiece and said hole in said socket and a pin to prevent its removal fromsaid socket.

In testimony whereof, I have hereunto I subscribed by name in thepresence of two subscribing witnesses.
